Silent Lift Check Valve
Brief introduction:
The silent resilient check valve is applied to the vertical pipelines in which medium flow runs upwards and the back-wards flowing are effectively stopped. It could be widely used in water-supply system and drain system and it works silence.
Features:
⊙Professional design
The inner cavity of valve is designed as streamline shape, which can effectively stop the turbulence. The spherical surface is introduced to form the front of disc and cone contact for the seating couple; these structures will extremely the shock force of medium and decrease the resistance coefficient of flow. Thin shell structures is employed when design the diversion component to ensure the laminar flow and greatly drop the weight. The reasonable open height and cavity space enable the obtaining of maximum area of flow section. It can avoid occurring of the air chamber; the valve parameter Cv is improved.
⊙Excellent proof corrosion characteristics
Internal and external epoxy resin coating.
⊙Reliable hygiene principles
Epoxy resin and rubber comply with hygiene standard, the trim, such as disc, spring, etc., are made of stainless steel.
